Cannot upload or backup to Amazon S3

bartv · October 12, 2015, 12:07pm

Hi,

we’ve been trying to set up backup to S3 in the 1.4 stable version, hosted on Communiteq (formerly DiscourseHosting). Our access keys are correct and we can upload through their CLI. However, Discourse throws the following errors (see dump below).

We found an issue that seems to be related:

github.com/aws/aws-sdk-ruby

"The request signature we calculated does not match the signature you provided." when uploading with `Aws::S3::Object#upload_file`

Travis CI has recently switched to use AWS SDK v2 for uploading artifacts to S3.… The up-to-date code is found at https://github.com/travis-ci/dpl/blob/master/lib/dpl/provider/s3.rb This works well for the most part, but a few isolated cases have been reported where the request signature does not match what's expected. 1. https://travis-ci.org/rebar/rebar3/jobs/79769044#L5696 (`Aws::S3::Errors::SignatureDoesNotMatch`) 2. https://travis-ci.org/octoblu/gateblu-forever/jobs/79543777#L409 (`Aws::S3::MultipartUploadError`) The code is quite simple: 1. Initialize `Aws::S3::Resource` with appropriate options (https://github.com/travis-ci/dpl/blob/75f10f342cc3e5d31c6cd45a2997966233d1deb6/lib/dpl/provider/s3.rb#L10) 2. And upload with `Aws::S3::Object#upload_file` (https://github.com/travis-ci/dpl/blob/75f10f342cc3e5d31c6cd45a2997966233d1deb6/lib/dpl/provider/s3.rb#L56) There is no custom signature generation from our code, so I am not sure what explains this exception. I appreciate any help. ref: https://github.com/travis-ci/travis-ci/issues/4776

Any ideas?

tests-passed and beta are not affected by this bug. Our hosted customers have this fix.

I am torn on updating this gem on stable, it feels like a bit of a risky move.

bartv · October 14, 2015, 12:33pm

Sorry, I don’t entirely understand what you’re saying. It’s correct that this is currently broken in 1.4 stable?

codinghorror · October 14, 2015, 6:30pm

Requires a gem update, is how I read it. Not our bug, technically, but requires recompiling against a newer gem version that handles this particular task.
